By using Remote Desktop Services (RDS), you can use Microsoft Outlook 2010 without upgrading every computer in your organization. Users can work in the latest Microsoft Office 2010 environment even when their computers have limited hard disk space, memory, or processing speed.

Remote Desktop Services lets you run Microsoft Windows–based programs on a server and display the programs remotely on client computers. For example, you can install a single copy of Outlook 2010 on a computer running Remote Desktop. Then, instead of running Outlook locally, multiple users can connect to the Remote Desktop computer and run Outlook from there.

By default, Remote Desktop clients do not have write access to the registry on the Remote Desktop computer, except to the registry hive under HKEY_CURRENT_USER. To run some Outlook features, you might have to give users write access to some keys and subkeys. For example, unlock the subkey HKEY_CLASSES_ROOT\CLSID to let users use the custom MAPI forms for Outlook 2010.
